To Reproduce

1. Visit the reproduction app.
2. In the app preview (dev mode), notice everything is working (/ page content is "OK").
3. Build the app (e.g. pnpm run build), and notice there are no errors.
4. Run the app in production mode (e.g. pnpm run start), visit /, and see a 500 error:

   Error: Invalid revalidate configuration provided: 0.999 < 1

Current vs. Expected behavior

Current behavior: an error is thrown in production only.

Expected behavior: in my opinion, the error check should be changed to < 0, and should be enforced at least during build time, if not also in dev mode.
